, application sied June ai, i925, serial no. aa'iaa l Y My inventionrelates to typewriting or like machines and more particularly to typeactions therefor.

The main'object of the invention, gener-A t ally stated, is to providean improved con-- struction and arrangement of parts whereby theelements .o f each type action are functionally and structurallycoordinated tov facilitate printing `in an' improved manner.

' More specifically stated, one of the objects of the invention is toprovide improved and highly eiiicient type actions for printing withoutproducing the noise that- -ordinarily results from the operation of the1 5v type actions.

A Suu .further @bieder the invention ist@ `provide any improved andhighly efficient;

construction of the character specified in which the type actions arecontrolled from a standard keyboard with a single shift.

Another' object of my invention is to so construct and arrangethepartsthat each type block at the last portion vof its printing guide andeffect an imprint with substanti-y ally a straightline movement. Afurther object of thevinvention is ,to provide improved means forarresting the return movement of each type bar and the parts connectedtherewith in a substantially noiseless manner and without rebound.

To the above and other ends which will hereinafter appear, my inventionconsists in the features of construction, arrangements of parts andcombinations' of devices set forth in the following descriptionandparticular# lly pointed out in the appended/claims.

lhave shown my invention embodied in the present instance in aRemington-Noiseless No: 6 machine,l but have only shown so much of saidmachine asis necessary to"- arrive at an understanding of the `inventionin its embodiment therein. It should be understood, however, that theinvention is not restricted to embodiment in such machin-e, but may beemployed in typewriting orlike machines generally, wherever foundavailable.

The present invention has some of the same general objects inview as thestructitl operated by either one of two keys. lEach pair of keys actuatea single front-stroke type bar in a substantially noiseless manner tonormally selectively print from one or another lower case type on thetype bar, depending on which of two keys is actuated, or to selectivelyprintV from one or another upper case type on the same type bar after arelative case shift has been ellected be tween the platen and type bars.

ln the present construction l have modified the means for controllingthe paths of movement of eachv type bar so that each bar moves at thelast portion of its printing stroke in substantially a straight lineinto the centerguide, and to the printing point,

as distinguishedfrom a type .moving in an up or down curved paththroughout its travel tothe printing point, as disclosed in myhereinbefore mentioned application, Sr. No. 3,365. This change providesfor more accurate guiding ot the type block and the provision of betteralignment of the imprints.

In the present construction l also have provided improved and highlyciiicient means for substantially. noiselessly arresting each type b arand the connected vparts in their return to normal position, and forpreventing rebound irom such normal position.

ln the present embodiment of my invention the frame of the machine maybe said to include a base 1 and so-called frame member 2 on whichvarious working parts of the machine, including the type actions, aresup ported. lt will be understood that the type bars are arranged in asubstantially hori- -zontally disposed arc in front of and around theprinting point as a center, so that each type bar moves but a shortdistance in a radial plane to the common printing center, as intheconstructions disclosed in my said eo-Apending applications. rllhecontrolling means for each type bar, with the possible exception in someinstances of the key levers therefor, move in the same plane as theplane of movement of the associated type bar, or as close to andparallel with such plane as the assembled parts will permit.

With the foregoing general statement lwill proceed to describe a singletype action, it being understood that allactions are alike,orsubstantially so, except that they are mounted indifferent planes thatvradiate from the. printing center. rlhe description of one Vtype actionapplies to the others.

Each type action 4comprises a flat substantially horizontally disposedtype bar or type carrying member 3 provided with a plurality ot typeblocks 4 and 5 fixed thereto. rlhe type block 4 has a lower case type 6and an upper case type 6a, whereas the type block 5 has a' lower casetype 7 for printing a diil'erent character and a companion upper casetype 7a, the printing neoaeeo faces of the types on the two blocks beingarranged in converging planes. Each type bar is guided against sidewisedisplacement in its printing movement by three fixed arcshaped guidecombs, c, a1, a2, having radial slots in which the type bars move. Eachtype bar is supported by a pair of links 8 and 9 pivoted respectively at10. and 11 to the type bar at diderent points in the length thereof; thelink 8 being pivoted to the type bar nearest the rear ortype-carryingend thereof. The link 8 extends as one continuous memberfrom the pivot 10 down to the lower end of the link -(see Fig. 5) whereit is provided with a laterally projecting pivot pin 12. A springretaining member 8a is riveted near one end to the link 8 and at theopposite end is spaced apart from the link and is adapted to bear on thetree end et' the pivotpin 12, and thus detachably connect the link 8tothe member on which the link is supported and pivoted.` rlhe lower endof the link 9 is mounted to turn on a pivot pin 13, and the links 8 and9 are thus mounted to swing respectively on the centers of the pivots 12and 13 in the movement of the type bar from normal to printing position.ln the present construction the pivot .pin 13 always remains iiXedduring. the travel of the type bar to printing posi-l tion, but thepivot pin 12 is arranged to be displaced Jfrom normal posi'fcvj:elw-vnd" Fig. 2,*dnring the travel of the compa-.

type bar under the actuation of one of its two printing keys. rlhe pivotpin 12 is mounted on a controlling member lll in. a,

bcaringbpening in which is received the pivot 12. 1n the presentinstance this mem- 1 ber 14 is in the nature of alever pivoted ati,y

15 on a headed pivot pin secured to a type action bracket -or hanger 16on which all associated parts oit the type acti-on except the key leversare mounted and by which they are supported, it being understood that ya separate hanger is provided for each type- 'lhe four-point' supportingmeans j action. for each type bar involving thepivots 10, 11, 12 and 13l term a quaternate or quaternal linkage. ',lilielever 14- in thepresent instance is angular in shape to avoid interference with otherparts of the type action,

as willbeunder'stood from an inspection of Fig. 2. llhe free end of thislever is pivoted at 17 to the upper end of a curved link 18 pivoted atits lower end, as at 19, to one arm of a bell crank lever 20. rlhis lastmentioned lever is pivoted at 21 on a stationary arm 22 that may beadjusted'to diderent set positions on the companion hanger 16,

as will hereinafter more clearly appear.`

The other arm ot the lever 20 is pivoted at 23 to a link 24 pivoted atits upper end, as at 25, to a leverarm 26 pivoted at 27 on theassociated hanger 16. rlhelink 24 and 'lever arm 26 constitute twoelements or 'reoaeao members of atoggle broken from its straight lineposition by one of the two printing l keys of the. type action and bywhich the position 'ot' the pivotal center of the link 8 is controlled.It will be seen that whenthe toggle is in the Fig. 1 substantiallystraightline holding position` line passes substantially -through thepivots 23, 25 and 27, the pivotal center 12 will be held fixed `at itshighest elevation. However, when the toggle is broken to the Fig.

2 position the center 12 is lowered to a dii.-

ferent elevation: y 1 from a comparison of Figs. 1 and 2 and `from aconsideration ofFig. 8 that in both these positions thel center 12 isapproximately on the same vertical line, and is at'substantially equaldistances respectively above and belowa horizontal line passing throughthe iulerum 15 of the-lever 14; y

The diagram represented in Fig. 8 is intended toshow the disposition ofthe links 8 and9 and their pivotal points .when the parts are-inprinting position under the ac-l tuation of either of the two associatedprinting keys` Referring particularlyto this figure, it will be seenthat due to the specific Construction, and to the relative arrangementof the parts shown, a straight line u drawn through the pivots 10 and12, when the last mentioned pi-vot remains fixed and 'companion type baris in the printing position, will when extended, intersect a straightline @..drawn through the pivots 11 and 13 of the link 9. This point ofintersection w i will be on a line ai tangential to the platen f Apointof intersection co the present instance of a\ whether the at theprinting point, and at a distance in inches above the printing point.-Moreover, this point of intersection w between the lines in questionwill be the mately the same, whether vthe pivot 12 be in the Fig. `1orin the Fig. 2 position. This is indicated in Fig. -8 wherein the line y`is' shown passing through the pivots 10 and 12 (shown in dotted lines)when they have been moved down to their Fig. 2 position. -The inquestion ymay be said to represent the instantaneous center on which thetype bar moves near and to the printing point, and which gives. asubstantially rectilinear movement to the effective type near theprinting .point at the last p0rtion oi. the printing movement'of thebar. The substantially rectilinear movement .in question isf-'one inwhich the effective-.type-I` type bar is actuated byone or the other ofits two printing keys, moves substantially in a straight linewhich ifprojected would pass through the printing point and the axis oi the bythe line e.

It may be here pointedout, however, that this construction and arrangement of the linkage tosecure the results stated is an Vimportant Vfactor ofA the presentinvention. `VVhile` theA diagram shown in' Fig. represents I correctconstruction and disposition ot' the points to give the propersubstantially rectilinear movement in question tothe enlective' typeasit approaches the printing point underl the actuation of either' of itstwo printing keys, it .should be understood that in lpractice thesepoints'may be slid'ably deviated from Iwithout suiiiciently interferingwith such movement in question as to make it objectionable. For example,if the lines' u c y should not all .converge at the point w,- or exactlyon the tangential line w, good results may be obtained nevertheless. Butthe closer the approximation to the points indicated the better will themechanism respond to the requirements pointed out.

I have hereinbet'ore pointed out that each type bar is operatedselectivelyv` by two printing keys. @ne key automatically brings one ofthe upper lower pair of printing position. arrange the printing-keys28,29, 30 and 31 in four banks,- with the key 29 in the second bank andthe key 31 in the fourth bank 'connected to one type action, as shown.The next type action willi-,have its keys 28 and 3() in the first andthird banks respectivelyl con` nectedt to the associated type bar. Inmoving a type bar to printing position under the actuation of the key 29the type 7 will follow a curved path indicated substantially by thedotted line ,ifthe parts have been properly adjusted. On the otherhand,when ,the type bar is moved under the actuation ot the key 31 thetype 6 will follow a curved .path 'of the general character indicated byThese curves are oppos'itel-y disposed and converge in front otand inline with the printing point, and complete their print-ing movement`from thenceto the platen substantially with arectilinear movementsubstantially coincident with the lineI a theoretically pair and'theother lone of the types on the type bar to fthe` f' In practice Iprefer--t`o"j4 paths of-nlovement ot' a type bar are eonl trolledinclude in part features which have been described, including the lever14 by .which the pivotal center 12 of the supporting link 8 may beshifted up and down from the Fig. 1 to the. Fig. 2 position. I will nowdescribe in detail how each type bar has .its path oit/movementcontrolled from its two. printing keys.I

, trolling toggle, as previously set forth.

' at 40 to the companion key The key 31 is carried by a key lever 32fulcrumed at 33 in the base of the machine and provided with anindividual returning spring 34. This spring is adjustably con# nected atone end to a depending arm 35 on said key lever, and is connecte-d atits other end with a bar 36 that extends beneath all of the key leversand is adjustably mounted by suit-able means in the base of the machine.The key lever 32 isdetachably connected to a link 37 by a pivot 38carried by .sa-id lever and received in an opening1 in the lower end ofsaid link. Asidebearing spring-plate or clip 39 is Apivoted lever andbears laterally at its free end against the link 37. This clip holds thelink connected to the lever` whenthe clip is in the eective positionshown, and' enables the link to be detached from the lever when the clipis turned vdown around its pivot 40. The upper end ofthe link is pivotedat 41 to' an actuating member, sublever or lever arm 42 pivoted at 27 onthe right-hand side of the bracket 16. This 'lever extends rearwardlybeyond* its pivot to' form a second lever arm 26 which constitutes, onemember of the con- Tn order to limit the movement of a toggle member 26,and the parts connected therewith, in both directions, T -provide anopening 43 in said member 26 to receive a stop pin 44 fixed to andprojecting laterally from one side of the bracket 16.V This stop pinco-acting with one side wall of the opening 4 3, as shown` in Fig. 1,will limit the return movement of the member 26 and the parts connectedtherewith. This prevents the toggle 24," 26 in its return movement frombreaking beyond the substantially straight-line normal position. Theeffect of maintaining the toggle in` the substantially straight-lineposition, is to hold the pivot 12 quiescent in the position shown inFig. 1 when the` type bar is moved to the printing position by theactuation of the key 29. However, )the depression of thev key 31 resultsin moving the member 26 to the position shown in Fig. 2, where theopposite side wall of the opening 43 coacting with the stop pin 44limits the movement of said member 26 and the parts connected therewithincluding the key 31. Thisdepression of the key 31 results in breakingthe toggle from the substantially straight line holding position, shownin Fig. 1, to

l the operated position indicated in' Fig. 2,

'thereby lowering the type bar supporting link 8 to change y the pivotalcenter 12 of the path of movement of the type bar to theprintingposition. The proper positioning of the pivot 12 in the Fig. 2position, and the holding of it in such position by the toggle, iseffected before the linal printing movement of the typebar takes place.

The @am printing key 29 Orth@ type' The lever arms 42 and 48 forward ofthe pivot 27 are parallel with each other and are of like construction,except that the arm 43 is provided `with a depending lever arm 49. Thisarm 51 which Lhas its rear end pivoted at 52 to a lever 53. The lever 53is pivoted at 54 on the left-hand side of the bracket 16 and is bent oroff-set laterally to form a yoke portion 55 above the bracket and isthence bent downwardly .to form a lever arm 56 onA the left-hand side ofsaid bracket and overlying the lever arm 26, for purposes which will nowappear. From an inspection of Fig. 2 it will be seen that the lever arm4S) is provided with an opening 49, the walls of which coact with thestop pin 58 on the hanger 16 to limit the motion of the member 43-49 andvthe parts connected therewith in both' directions, like thecorresponding stops of the member 26, 42.

llt will be understood that after each breaking of the toggle 24, 26from the Fig. 1 to the Fig.y 2, position by an actuation of the key 31,the returning spring key isintended to return the toggle to normalstraight-line position when the operator releases the key. However, itmay happen at times that the toggle 24, 26 has not completelyreturned tosuch position before an actuation of the type bar by the other key 29takes place. It is in order to rectify the position or insure thecomplete return of the toggle,"and thus t0 maintain an aecuratepositioning of the pivotal center 12 in the Fig. 1 position, that Tprovide the lever 53, 56 operating in the manner described. Thus, itwill be understood that a depression of the key 29 will, lthrough theintermediate train of connections 46, 48, 49, 51, and 53, lower the arm56. 1f the toggle 24, 26 had not been fully returned after the precedingoperation of the type bar by the key 31, then the part 26a ofthe member26 will extend in the path of the arm 56, and as the latter is moved`down under the actuation of the key 29 the member 26- will be forced tothe limit of itsgreturn movement, or until it coacts with the stop 44 inthe F ig. 1 position. This occurs before the type bar reaches theprinting position under the action of the key 29, and 1nsures the properpositioningl of the pivotal 34 for said' 49 is pivoted at 50 to a linklll) v the associated bracket 16. It willl be under- .stood that vin.the present instance Ijcon `\\able means,

andti tending arm cach type bar is moved to printing position.

In the present construction, like those olisclosedv in my-said copendingapplications, AI employ a single train yof driving means or cnnectionsfor each type action including motion governing means having la momentumaccumulator, said governing means being arranged to decelerate the finalprinting movement ot the type 4bar and'to translate into pressureagainst the platen the kinetic such means combined with the parts previously described that an -imprint may 4be effected in substantially anoiseless manner.

Operating motion is transmitted to `each type barfrom botli ol' itsprinting keys through the above-mentioned single train of driving means,to a'ctuate each type bar with a substantially uniform :touch from both`its `keys and to provide a` uniform, or substantially uniform, touch onthe keys throughout the-system.

It has' been explained that the independe ently operating lever arms-42and 48 for- Ward ot' their common pivot 27 are `of uniform character'and are mountedto move in parallel p lanes. A main driving'flever 57 isprovided in each type action, this lever being pivoted at 57a to adepending arin on struct each` of these levers from vtwo correspondingly'shaped members spaced apart aiid'lield together in spaced relation bysuitsuch as shouldered rivets.' The cispeetion of each of the drivinglevers connections therefrom to the type bar may \be the same, orvsubstantially the t`ione\d application,l Si".

In orderto insure contact between the. `co-, acting lever arms 6l, 42 and 48, ,Iprovide in the present construction a guide comb 65 secured at its upperend, as at66, to the associated .hanger 16.l The coacting lever armswork in guide slots 67 in the comb and. are thus maintained againstrelative lateral displacement. A depending link 68 is plv# oted on arivet 69 ot' each driving lever 57 and is forked ati'ts lower end tocoact with a segmental universal bar 70A which controls.

the escapement (not shown) for the carriage.` lever 574 also .hassanupright double arm 7l comprising ptwo correspond- `ing parts whichstraddle the bracket 16 and are united at their upper ends by a pivotpin 72.- This double arm 7l` is'connected to the associated typel bar 3through mechanical devices which together with the main driv- -ing lever57 constitute what has been hereinbefore rei-'erred to as a single trainof drivii g connections including motion governing means having amomentum accumulator.

Such means are etl'ective vto transmit a for- Ward thrust to the typebar .in a uniform manner whetheractuated b y one or the other associatedkeys 29 and 3l. This train of connections includes a toggle comprising adoubletoggle link 7 3 made up of'tWo correspondingly shapedinembersgconnected tof gether but maintained spaced apart.- Thertoi-ward end portions of the'members of this double link-73 extend onopposite sides of the type `bai-,and are. connected thereto by the'pivot ll which also connects the sup-4 porting link 9 to the type bar.1A second double toggle member. 74'is made up 0'1" two correspondinglyshaped' united parte which are maintained spaced apart. member 74 ispivotedat 75 to the forward end of the link 73 and extends on oppositeturn ouv a. fixed pivot 76 carried by said hanger. A. single.'link orlever. arm 77 is connected at onerend bythe pivot 72 to the upright.doublearm 7l of the main driving lever. The arm 77 extends between thetWo members vvhich constitute lthe toggle inember 74 and is p'votedthereto at one end, as at 7 8, and moves the toggle 7 3, 74 to the sub-,stantially straight line position represented in Fig. 2,-.to applyprinting pressure along thestraight line of the toggle. Rigidly attachedto the arm 77 is a comparatively heavy Weighted member- 7 9 whichservesas a momentum accumulator fdrthefactuating toggle 73, 74 when thelatter is actuated by the main driving lever 57. After the de` pressionojf a printing key has been arrested, the momentum of the' accumulator79 Will continue its movement to impart 'its energy to the toggle inorder to complete the movement of the toggle members to 'the sub- I Thisdouble 'si-des of the hanger 16 and is supported-to l 60 tions as 'willpresently appear.

stantially straight line position, thereby completing the printingstroke of the type bar. It will be seen therefore that this momentumaccummulator 79 -is adapted to supply the 6 final energy necessary to straighten the toggle 78, 74 when the type bar has sub- AAWstantiallyreached the printing position.

` 'A contractile spring 8O is connected at one end to the bracket 16 andat the other end of the rivet 69 onthe driving lever 57 and4` serves toreturn the lever 57 and the parts connected therewith to the .normalFig. 1

position afterr each actiiation,tlie key lever being independentlyarrested in its return l5 movement by the stop 44 or 58, or if desiredby a l,padded stop or rod el. I have embodied nove means in the presentconstruction associated` with each typefaction, for substan-`tially'noiselessly arresting the return move- 20 nient of the type barand the train'of driving connections therefor withoutirebound from theposition of arrest, which l will now .de-

scribe. j

Referring more particularly to Figs. `8 and 4, it will be seen that a'pair of toggle members or links 81 and 82 are united at their adjacentends by a headed pivot pin 83. This pivot is rivetedto the link 82 andworks loosely in an inclined slot 84 in the link 81.

The width f this slot is such that the'pin maybe received `therein witha free sliding fit. The slot extends longitudinally upwardly andforwardly towards the forward end of the link 81 at slightly less than aright anigle to a straight line f (Fig. 8) that passes through thepivots 83,85 and 86 of the links when the, parts areI in the normalposition, shown in Fig. 8. The reary end ofthe link 81 has acorresponding slot 87 except that it 0l is inclined'in the oppositedirection from the slot 84. The 'slot 87 receives a headed pin 85secured'to the associated bracket'or hanger 16 to which the pair oflinksis anchored.

The headed pivot pin 86 is fixed to the weighted member 79 and the link82 which.

is pivoted on this pin is maintained spaced apart from the weight by aspacing sleeve 88. The forward end of the link 82 extends beyond itspivot 86 and forms a forwardly tu extending stop projection or finger89. 'I his stop vprojection is adapted,' under certain conditions, tocoact' with a laterally projecting stop pin 90 on the member 7 9, but isnormallv out of Contact therewith. Gravity and i lili the reaction ofthe parts tend to maintain the" parts so that each of the pivot pins 85and 88 is normally seated in the'upperend of'its respective slots 84,87, but under certain'con'- j ditions there may be a change intheserela- In the operation of the stop links, the returnof the type bar andits train of driving l connections from a projected position, such as isshown in Fig. 2, will tend to bring the w links 81 and 82 from Itheangular position shown in said figure to a `substantially straight-lineposition, shown in Fig. 8. lVhen the parts reach this last' mentionedposition the links 8l and 82 will eflfcct a dead center pull`against thefixed pivot 85 and arrest further movement of the parts in substantiallya noiseiess manner` and 'without rebound. By arresting the returnmovement ot'k the parts in the manner described the. straightened linksabsorb the spring of the moving-parts a-nil there is practically nobound or noise produced in effecting the ai-rest; lf for anyrcas0n lthepivot pins 85A placement to break the links from their,

straight-line position and prevent the links .from locking the actionagainst operation or from interfering with theA printing move-- ment ofthe parts.

The stops 89 and 90 prevent the links from accidentally jolting upwardlya' material distancg beyond the straight-line position in the return ofthe parts to normal. position. By having the stops normally out ofContact, and having them coact only occassionally when the connectedends of the links jolt up too far, l avoid the slight` noise that 'mightresult by reason of the stops contacting at every operation of the typebar.

Y In the present construction the alignment of ther type bars isobtained by an inclined adjustment of the supporting arm 22 by vwhichthe. pivot 21 is carried. f The degree of the angle of this adjustmentin the present instance differs from that in my application Sr. No.3,365, due to other changes made in the. present type action, but theresult obtained is-the same. In the present instance I employ thisone'adjustment only of the member 22, andto effect it ll provideinclined slots 9,1 and 92 in the member 22, the inclination of the slotscorresponding to the line of adjustment ofsaid member 22. Two guidepinsi 98 and 94, the latter` being headed, are received in the slot 91,whereas two guide pins 95 and 96 are received in the slot 92, said pinsprojecting from the left-A hand side of the associated bracket or hangerThis' is due tothe inclined slots slotted ends of 16. An eccentric 97 isreceived in a slot 98 't in the member 22, said slot extendinglengthwise at'substantially right angles-to the slotsv 91 and 92. 'Theeccentric 97 is provided'with a hexagonal head by which it may be turnedto adjust the member 22 in the direction of the length of the slots 91and A92 therein. A

' screw 99 carried by the bracket and on which the link 9 is supported,may likewise be .ad-.

justably supported on .the companion bracket 16 by pivoting' the arm onthe bracket at 101. The .forward end oil-this arm.100 ymayl have 'alongitudinally extending slot 102 therein, in which is seated aneccentric ro-` vided with a hexagonal head 103 and abinding 4screwhaving -a corresponding head 104 to hold the eccentric in its. adjustedlposi.a tion. The adjustment of the arm 100 lto different setpositions-on the bracket 16 and around the pivot 101, results in raisingor. lowering the pivot 13 ofthe link 9.- As

hereinbefore indicated ythe adjusting'me'ans herein disclosed lhaveV thesaine objects lin view as the corresponding adjusting means disclosed inmy copending application, Sr. No. 3,365.

It has-been explained that a separate supporting bracket or hanger .16is provided foreach type action. These brackets are-radially disposedaround the printing point, means Vbeing provided Awhereby each bracket,to-

gether with the parts ofithe type action carried thereby, may beindividually introduced into and removed from the machine as a separateunit, and may receive an individual adjustment radially towards and fromthe' printing point. The construction that enables these results yto beobtained is'the same as disclosed in my copending application; Sr. No;3,365, and is as follows: V The. forwardhorizontally disposed porl tion,105 of each bracket 1 6 is received in a of the machine.

radially disposed slot in the top of the mem bei' 2 lof the machineframe?

from the machine. The guide comb of each type action being individualthereto, and to the hanger or bracketby which the associatedtype actionis supported, enables the above mentioned results to be readily atlThepresent invention contemplates effecting a' relative case shift movementbev 95 tween the platen 114 and the type bars. Any suitablemeans may beemployed for j this purpose, such for example as the pliaten shiftingmechanism disclosed in my application, Sr. No. 14,100 filed March 9,1925. In ^the present construction a shift key 115` (Fig.- 1) maybeassumed to actua-te suitable means (not shown) to shift 'the platenfroml the lower case full-line to the upper case dotted line positionshown inFig. 1.` In 95. Fig. 2 I haveshown a lower case type 6 on thetype block 4 at the printingpoint under an actuation of the key'31.A-depression of the key 29 will bring a lower case type 7 on the typeblock 5 to -the printing point when 100 the platen isin the full-lineFig. 1 position. When the platen is shifted to' the 'upperl case dottedline position, then one ofthe upper case types 6a or 7 a will beselectively' moved to the printing point, depending on which of the twoassociated printing keys 29 or 31 'rolling tread on this lever eoactingwith the companion-'rolling tread on the double arm A61.0f the drivinglever 571gives a variable acceleration. to the motion. of the latter andalso providesl a llost motion connection be- '115 This lost motion isbrought aboutwhen 'the motion of the .lever 48, land thekey 29 by whichit is actuated, a-re brought to rest at. the end of their stroke. "Atthis time, the driving lever 57 12,

and the parts connected therewith, including the typebar, are permittedto continue their operation independently' ofY the lever 48 and undertheir own momentum', to effect an imprint'withut the impetus of theactu-125 atedf key 29 and the parts connected therewith at the final portionof the printing stroke. The motion thus transmitted to the` type bar 'isin the nature of a thrust exerted through the toggle members 73 and .74.pushmi cated in ing the typebar to the printing point and by the final.expenditure of energy apply a powerful printing pressure. rlhe printingoperation of the type bar by anl actuation of thev key 31 is accompaniedby a displacement of the pivotal `center 12 of the supporting'link 8, asshown in Fig. 2'. This is accomplished by breaking the toggle 24, 26from its substantially straight' line position, shown in Fig. 1., to theposition represented in Fig. 2, due to the actuation of the lever arm 42with which the toggle has direct mechanical connection. This results inturning the lever on its pivot 21 and lowering they support-ing leverfrom the Fig. 1 to the Fig. 2 position, as hereinbcfore explained,tlicreby changing-the position of the pivotal cen.- ter 12 of thesupporting link 8 and causing the type bar to travel through a differentcurved path from that which it follows when actuated by the key 29, alsindicated by a comparison of the dotted lines I), c in Fig. 1.

An actuation of the type bar b v the key 29 produces a like movement ofthe single train of connections from-the driving lever 57 to the typebar. In this instance, however, the toggle 24, 26 remains at rest in thesubstantially straight-line position, as indi- Fig. 1, thereby holdingthe lpivot 12 fixed against movement while the' link 8 turns thereon.Thisresults in the type bar moving in a curved path. indicatedsubstantially by the ydotted line b in Fig. 1, to print from one or theother of the types or 7a,

depending on `whether the platen is in the lower or upper case positionto receive the impress of the corresponding type. A return movement ofeach type bar and the4 driving connections therefor to normal posi@tion, whether actuated by the associated key 29 Ior 31, is arrested bythe links 81 and S2,

as hereinbefore explained.

In the present construction I am enabled to employ a center type guidedthat closely 'and effectively guides the type blocks both up and down,as well as sidewise, by reason of ythehereinbefore describedsubstantially straight-line movement given to the 4type block at thelast portion of the printing .1novement, and while it is enteringthe'type guide (Las will be clearly understood .from

aninspectionof Figs. land 7.' vAs shown in Fig'th'e fixed centerguide dhas upper anl important and. 'lower guide walls 11G, 117 respectivelyand oppositely disposed side 'walls 118 and 1719 which cf'i'act with',each type block- 4 or 5 as'iit'squarely lenters the guide and accuitAtov the printing point` thus providing'foraccurate alignment. This isfactor in a, machine of this character andfthe said striglit-linernove-l ment. of the effective type block at the last part v'oftheprinting 4movement renders it feasible to thus accurately guide thetype.

. Corresp 1t will be seen thatA in the present con-y struction thesupporting and guiding links 8 and 9 merely act as suclf'at all times,the driving operation of the type bar being never effected through. saidlinks, and that whether the type bar. be driven by the actuatiorrof oneor the other of the keys 29 or 3-1'such driving ope-ration, as such, iseffectedindependently of saiddinks, and always through the separat-e anddistinct single driving train from and including' 'the lever 57, whicheX-. erts at all operations a thrust on the type bar to move to.printing position always in a uniform manner.,

1t will be understood, moreover, that the pivotal support for the link 9is at all times nuiintainedfixed during the printing operation, whetheroperating the type action from the key 29 or 31, and that the presentcontion, aud results to a high degree in a snnple,.uniform accurate,noiscless and reliable printing operation .thatmay be controlled by astandard keyboard.

Vhile I have described in considerable detail the constructional form ofthe 'vari- Vous members which go to makeup each type action, vI am awarethat various changes may be made in the construction, and that certainparts. may be employed without others, without departing from. my inven'tion as it isv defined in the accompanying claims. However, the form ofconstruction shown and described/ has proven reliable and eificientinuse.
